How to Install an SSL Certificate on Ubuntu

Hello! Installing an SSL certificate on Ubuntu can involve several steps. First, you need to obtain an SSL certificate. This can be purchased from an SSL certificate provider or a self-signed certificate can be created for free.

If you are using a purchased certificate, download the certificate files provided by your provider (usually .crt and .key files) to your computer. If you are going to create a self-signed certificate, follow these steps:

1. First, install the OpenSSL package. This can be done with the command “sudo apt install openssl” in the terminal.
2. Create a private key file using the “openssl” command. This can be done with the command “openssl genrsa -out private.key 2048” in the terminal. This command will generate a 2048-bit private key file.
3. Create a CSR (Certificate Signing Request) using the private key file. This can be done with the command “openssl req -new -key private.key -out csr.pem” in the terminal. This command will ask you several questions and collect information about the certificate.
4. Create a self-signed certificate using the CSR file. This can be done with the command “openssl x509 -req -days 365 -in csr.pem -signkey private.key -out public.crt” in the terminal. This command will create a certificate using the CSR file and sign it for 365 days.

If you are using a purchased certificate, follow these steps:

1. Copy the certificate files to the directory (/etc/ssl/certs).
2. Copy the private key file to the directory (/etc/ssl/private).

Installing SSL Certificate on Nginx on Ubuntu

Hello! To install an SSL certificate on the Nginx web server on Ubuntu, follow these steps:

Edit the Nginx configuration file. This file is usually located in the “/etc/nginx/nginx.conf” directory. As shown in the example below, you need to specify the certificate and private key files.

First, obtain the SSL certificate. This can be purchased from an SSL certificate provider or a self-signed certificate can be created for free. If you are creating a self-signed certificate, please follow the steps outlined above.

Copy the SSL certificate and private key files to the directories used by Nginx. The private key file is typically copied to the “/etc/ssl/private” directory, and the certificate file is usually copied to the “/etc/ssl/certs” directory.
